I wonder if I can attach one of these to my keys, cell phone, loose $5 bills, or perhaps even my own head. Garmin’s little waterproof GTU 10 gadget is a portable GPS locator that combines a web-based tracking service with GPS technology so you can keep a close watch on children, pets and property. Or, let’s be totally honest, that shady ass girl you’re dating who has to keep going “home” to help “mom” because she can’t “feed” or “care for herself” since the “stroke.” Likely story, Wendy. The Garmin GTU 10 even has extra features such as the ability to alert you once a preset boundary is crossed, or keep a history of its whereabouts. You know, to make sure Wendy’s “mom” doesn’t live in the same apartment building as her weed dealer. If you want to keep some peace of mind, at only $200 the GTU 10 is an inexpensive, excellent device… homing device, that is.
